Recreational Sports and Intra-articular Hip Injuries in Patients Undergoing Hip Arthroscopy for Femoroacetabular Impingement

Return-to-Sport Rates After Hip Arthroscopy for Femoroacetabular Impingement Syndrome in Flexibility Sports Athletes: A Systematic Review

CONTEXT

Femoroacetabular impingement syndrome (FAIS) is a common cause of hip pain in young adults. Flexibility athletes represent an interesting subset due to the extreme range of motion requirements of their sport.

OBJECTIVE

The objective of this review was to provide a summary of the outcomes of hip arthroscopy for FAIS in patients who participate in flexibility sports.

DATA SOURCES

Three online databases (Medline, Embase, and PubMed) were searched from database inception (1946, 1974, and 1966, respectively) to January 10, 2023.

STUDY SELECTION

Studies were screened for literature addressing surgical outcomes for flexibility athletes undergoing hip arthroscopy for FAIS.

STUDY DESIGN

Systematic review.

LEVEL OF EVIDENCE

Level 4.

DATA EXTRACTION

Various patient-reported outcomes that evaluated the efficacy of hip arthroscopy in this patient population were abstracted and presented in descriptive and analytical format. Abstraction was performed by 2 reviewers.

RESULTS

Overall, a total of 8 Level 3 or 4 studies and 295 patients (312 hips) were included in this review. The pooled standardized mean differences for the Visual Analog Scale for pain score, Modified Harris Hip Score, Hip Outcome Score - Activity of Daily Living scale, and Hip Outcome Score - Sport-Specific Subscale all demonstrated significant improvement after undergoing arthroscopy for FAIS between 12 and 116 months (N = 175, -1.97, 95% CI -2.5 to -1.4, P < 0.01, I2 = 76%; N = 211, 1.82, 95% CI 1.49 to 2.16, P < 0.01, I2 = 52%; N = 164, 1.75, 95% CI 1.42 to 2.05, P < 0.01, I2 = 28%; N = 211, 1.71, 95% CI 1.38 to 2.04, P < 0.01, I2 = 52%, respectively). Across 289 patients, 75.6% to 98% returned to sport at a similar or higher level than presurgery.

CONCLUSION

This review demonstrates a trend of improvement in patient-reported pain, function, quality of life, and return to sport at a minimum of 12 months among flexibility athletes after hip arthroscopy to treat FAIS.

La necesidad de mejorar las competencias de los futuros profesionales en salud ha conducido a repensar la manera como se imparten los conocimientos a los estudiantes y de cómo ellos podrían aprender de manera significativa. Actualmente, el aula invertida (AI) o flipped classroom (FC) se convierte en una estrategia de enseñanza alternativa en el campo de la educación en salud. Incentiva el aprendizaje del estudiante al promover la autonomía en el abordaje de los conocimientos antes de cada clase, favorece la motivación, el aprendizaje activo, colaborativo y significativo durante las sesiones presenciales, de tal manera que permite desarrollar el pensamiento crítico para una formación profesional idónea. Al realizar una revisión de la literatura se evidenció un amplio uso del AI en educación en salud con resultados positivos frente a la educación tradicional. Además, las tecnologías juegan un papel importante para presentar contenidos y ejecutar actividades fuera y dentro del aula. Se presentan algunas evidencias de la efectividad del AI en educación médica, cómo podría implementarse en nuestras aulas y la diversidad de recursos disponibles para usar en los diferentes escenarios que plantea esta estrategia.

Hip Pain Increases With Age and Experience Level in Adult Karate Athletes: A Statewide Survey Study

Purpose

To investigate the prevalence of hip pain from labral tears and femoroacetabular impingement (FAI) in karate athletes using a statewide online survey.

Methods

An anonymous electronic survey was distributed via Qualtrics to all registered members of a statewide karate organization who were a purple belt or higher. Basic demographic information was collected as well as belt level, competitive level, and information regarding hip pain and treatment for hip pain. Microsoft Excel was used to store and analyze data.

Results

Of 180 respondents, 123 (68.3%) never had hip pain when practicing karate, and 54 (30.0%) had hip pain at some point in their karate career. Three subjects did not provide an answer and were excluded. Furthermore, of the symptomatic individuals, 52 reported the location of their hip pain, whereas 2 subjects did not. Of the symptomatic individuals (54), 32 had formal diagnoses by a medical professional, 4 (12.5%) were diagnosed with FAI of the hip, 6 (18.8%) diagnosed with a hip labral tear, 3 (9.4%) diagnosed with hip bursitis, 3 (9.4%) diagnosed with hip arthritis, and 16 (50%) had other diagnoses. The remaining 22 participants have not received a formal diagnosis by a medical professional.

Conclusions

The prevalence of hip pain in karate athletes in this survey was lower compared to athletes of other martial arts and kicking sports. No differences in the percentage of injuries were found between sex and years practiced; however a higher incidence of hip pain was found between elite status and age group. When evaluating hip pain in the karate population, orthopaedic surgeons should maintain an index of suspicion for FAI and hip labral tears.

Level of Evidence

Level IV, retrospective cross-sectional study.

Pathologic Findings on Hip Arthroscopy in High-Level Athletes Competing in Flexibility Sports

BACKGROUND

Athletes who compete in flexibility sports (FS) place unique demands on their hip joints because of the supraphysiologic range of motion required.

PURPOSE

To compare the pathologic features, outcomes, and return-to-sports (RTS) rates of high-level athletes participating in FS who underwent hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and labral tear against a propensity score-matched cohort of high-level athletes participating in non-flexibility sports (NFS).

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

Data were prospectively collected and retrospectively reviewed for high-level athletes who underwent primary hip arthroscopy for FAIS from April 2008 to December 2018. Patients who participated in FS such as dancing, gymnastics, martial arts, figure skating, and cheerleading were propensity score matched by body mass index, age at time of surgery, sex, sports competition level, and labral treatment to a cohort of high-level athletes participating in all other sports, such as distance running, soccer, volleyball, and softball. Baseline patient characteristics, intraoperative findings, and surgical procedures were compared. Minimum 2-year patient-reported outcome measures were compared for the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sport Specific Subscale, and visual analog scale for pain and satisfaction. Rates of secondary surgery and RTS were compared.

RESULTS

A total of 47 patients (50 hips) who participated in FS were included and propensity score matched to 130 patients (150 hips) who participated in NFS. Follow-up time was 37.5 ± 10.4 months (mean ± SD). Most patients (96.0%) were female with a mean age of 19.5 ± 7.3 years. FS athletes had significantly higher rates of femoral head cartilage lesions (Outerbridge ≥2; 12.0% vs 2.0%; P = .008) and ligamentum teres tears (48% vs 26%; P = .003). FS and NFS athletes demonstrated significant clinical improvements after surgery for all patient-reported outcome measures. Of the patients who attempted, 34 (75.6%) participating in FS were able to RTS while 11 (24.4%) were not because of ongoing hip issues. This was not significantly different than the NFS group (P = .073).

CONCLUSION

High-level athletes who participated in FS and were treated for FAIS with hip arthroscopy exhibited higher rates of femoral head cartilage lesions and ligamentum teres tears requiring debridement when compared with a benchmark group of athletes who participated in other sports. Despite this, both groups demonstrated similar improvements in outcome scores and comparable rates of RTS at minimum 2-year follow-up.

Evaluation of outcome reporting trends for femoroacetabular impingement syndrome- a systematic review

PURPOSE

The aim of this systematic review was to evaluate the trends in the literature regarding surgical treatment for femoroacetabular impingement syndrome (FAIS) and to present which patient-reported outcome-measures (PROMs) and surgical approaches are included.

METHODS

This systematic review was conducted with the PRISMA guidelines. The literature search was performed on PubMed and Embase, covering studies from 1999 to 2020. Inclusion criteria were clinical studies with surgical treatment for FAIS, the use of PROMs as evaluation tool and studies in English. Exclusion criteria were studies with patients < 18 years, cohorts with < 8 patients, studies with primarily purpose to evaluate other diagnoses than FAIS and studies with radiographs as only outcomes without using PROMs. Data extracted were author, year, surgical intervention, type of study, level of evidence, demographics of included patients, and PROMs.

RESULTS

The initial search yielded 2,559 studies, of which 196 were included. There was an increase of 2,043% in the number of studies from the first to the last five years (2004-2008)-(2016-2020). There were 135 (69%) retrospective, 55 (28%) prospective and 6 (3%) Randomized Controlled Trials. Level of evidence ranged from I-IV where Level III was most common (44%). More than half of the studies (58%) originated from USA. Arthroscopic surgery was the most common surgical treatment (85%). Mean follow-up was 27.0 months (± 17 SD), (range 1.5-120 months). Between 1-10 PROMs were included, and the modified Harris Hip Score (mHHS) was most commonly used (61%).

CONCLUSION

There has been a continuous increase in the number of published studies regarding FAIS with the majority evaluating arthroscopic surgery. The mHHS remains being the most commonly used PROM.
